PUMPER

/WgUSDT

Pumper is a token launch protocol built on Uniswap V3, deployed across multiple EVM-compatible chains including Stable, with additional deployments on Robinhood Chain, Base, and Arc. It allows anyone to create a new token through a permissionless launch process: every launch mints a fixed supply of 1,000,000,000 tokens with no custom supply, tax, or burn configuration available to the creator, and 100% of that supply is seeded as one-sided liquidity into a Uniswap V3 pool at a fixed 1% fee tier, split across two adjacent price ranges so that upward price movement is never capped. The resulting liquidity position is permanently locked: there is no function in the contracts that allows the creator or the protocol to withdraw it. Trading happens through standard Uniswap V3 swaps with slippage protection, with no separate creator-imposed fee or tax on top of Uniswap's own 1% swap fee. Anyone can permissionlessly trigger a harvest of a pool's accumulated swap fees; the token-side portion is sent to a burn address, and the pair-token side is split between the protocol, a reward pool, and (depending on launchpad version) an automated buy-and-burn mechanism for a designated community token. The protocol also includes a native token/LP locking system (`PumperTokenLock`/`PumperLPLocker`), a swap aggregator that routes across multiple on-chain venues (Uniswap V3 and DYORswap V2) for execution, and an on-chain governance module tied to its own token, $PUMPER.
